APPENDIX 8-G. REBUTTABLE PAYBACK ANALYSIS RESULTS 

8-G.1 INTRODUCTION 

This appendix contains the cost and efficiency tables described in chapter 8. DOE 

based the payback periods on the calculation methodology found in the DOE room air 

conditioner and clothes dryer test procedures; these payback periods may differ from 

those found under field conditions. 

8-G.2 ENERGY CALCULATIONS 

8-G.2.1 Room Air Conditioners 

The energy consumption in the LCC analysis is determined using the DOE test 

procedure. The DOE test procedure calculates annual energy consumption, Eannual, as 

follows: 

Eannual = Capacity ×(Hrs /1000) / IEER

Where: 

Capacity = room air conditioner input capacity, 


Hrs = room air conditioner operating hours (750 hrs), and 


IEER = room air conditioner efficiency. 


8-G.2.2 Clothes Dryers 

The energy consumption in the LCC analysis is determined using the DOE test 

procedure. The DOE test procedure calculates annual energy consumption, Eannual, as 

follows: 

EF = Cycles ×(Lbs / IEF) 

Where: 

Cycles = clothes dryer cycles per year, cycles/yr, (416 cycles/yr), 

Lbs = pounds of clothing, lbs, (7 lbs for standard and 3 lbs. for compact 

dryer) and 

IEF = clothes dryer efficiency. 

8-G.3 RESULTS TABLES 

Tables 8-G.3.1 to 8-G.3.10 show the rebuttable payback period calculation results 

for each product class.
